4 Claims.

This invention has relation to that type of bobbin stripping machines having blades or the like by which the bunch of weft or lling is removed from the bobbin-barrel by a scraping action taking place lengthwise along the bobbin barrel, and the object of this invention is to provide a head-rest for the bobbin which shall have certain advantages hereinafter described, over the usual type of head-rest, such for instance as is shown in my former Patent No. 1,740,127, dated December 1'7, 1929.

In the drawing annexed, Eig. 1 is a side elevation of a portion of a bobbin stripping machine showing my invention applied thereto, and Fig. 2

is a plan view of the same.

Referring to the drawing annexed by reference characters, 5 designates the two reciprocating scraper blades having their inner ends provided with arcuate scraping edges, as usual. These blades are mounted in supports 6 which are stationary parts of the machine frame. Mounted on the supports 6 is a pair of plates l which together form a head-rest for the bobbin head, one of these blades being attached to each of the supports 6 by a lag bolt 8 which passes through a longitudinal slot 9 in the plate, and is tapped into the support 6.

Each head supporting plate 'l is inclined upwardly toward the center of the path of the 30 bobbin, the head of the bobbin being shown in dotted lines at I0. The seats for the plate 1 are inclined their full length so as to provide a solid substantial support for the plates, and in order to prevent the plates turning on the bolts as pivots, I provide each support 6 with an integral flange Il which engages the adjacent edge of its companion plate. The inner, upper edges of the plates 'l engage the usual rings on the head of the bobbin and thus support it in proper position for its barrel to be grasped by the scraping blades. 5. Plates 'l are made alike at both ends so that they are not only interchangeable, but reversible, end for end, thereby facilitating assemblage of the parts.

By using two blades, one at either side of the path of the bobbin and making each one independently adjustable toward and from the center of the path of the bobbin, it will be seen that the bobbins may be nicely centered with reference to the scraping blades irrespective of the size of the bobbin head. This independent adjustability of the head-rest plates does away with the necessity of exercising that great accuracy in designing the head-rest that is needed where the head-rests are made stationary. Also, the adjustable plates are highly desirable in that they 5 permit the mill to adjust the machine to suit the head sizes of its bobbins, thereby doing away with the expense and delay of having the head rests removed from the machine and reshaped.

By inclining the head-rest plates upwardly to- 10 ward the center of the bobbin path I get a furtherI important advantage in that I provide a wider throat space between the two supporting plates than is possible to obtain with the former horizontal head-rests, and thus provide a wider 15 space for misplaced yarn-bunches to fall through.

It occasionally happens that yarn-bunches will be flipped over onto the head-rest and lodgedl thereon with the result that the next bobbin delivered onto the head-rest will have its head propped up suiciently to prevent the bobbin barrel being embraced properly by the scraper blades. It will be seen therefore that it is highly desirable to have the space between the headrest elements as wide as possible as the wider it is the less danger there is that a misplaced yarn bunch will lodge on the head-rest members.

I claim:

1. In a bobbin-stripper, frame members, a pair of stripping blades, and a bobbin head-rest adjacent said blades, said bobbin head-rest consisting of a pair of plates both inclined upwardly and supported on the frame members, one at each side of the bobbin path, and means whereby said plates are rendered adjustable toward and from the bobbin path.

2. The structure recited in claim l, said plates being inclined upwardly toward the center of the bobbin path.

3. The structure recited in claim 1, the means for adjustably fastening the plate-s to the frame members consisting of longitudinal slots in the plates and bolts passing therethrough and serving to clamp them against the frame members, said frame members being provided with depending flanges which abut the side edges of the plates.

4. 'Ihe structure recited in claim 1, said blades being each also removable and reversible end for end, both ends of each blade being shaped alike.
